Anatomy and physiology of eustachian tube Biology Diagrams The Eustachian tube is named after the Italian anatomist, Bartolomeo Eustachi, who observed that it was a canal that connected the nasopharynx to the middle ear. The Eustachian tube is also known as the pharyngotympanic tube or the auditory tube.[1][2] The Eustachian tube (auditory or pharyngotympanic tube) is a canal that connects the tympanic cavity (of the middle ear) to the nasopharynx. It is derived from the embryonic first pharyngeal pouch. It is a distinct organ which plays several roles in auditory physiology. Aeration of the middle ear - creating equal air pressure on both sides of the tympanic membrane.
Patulous Eustachian Tube . In most people, the eustachian tubes open without a problem whenever the air pressure changes, such as when flying in an airplane or diving underwater. However, in some people, the tubes have a harder time equalizing the pressure. As a result, people may have temporary ear pain when they are in these situations. The Eustachian tube, also known as the pharyngotympanic or auditory tube, is a vital structure within the ear anatomy, playing a crucial role in maintaining the pressure balance between the middle ear and the external environment.. Location. The Eustachian tube extends from the anterior wall of the middle ear to the lateral wall of the nasopharynx, the upper part of the throat behind the nose. Eustachian tubes connect your middle ears to the back of your throat. The tubes help drain fluid from your middle ear and balance air pressure inside your ears. Allergies, colds or infections can cause eustachian tube dysfunction. This is a broad term for issues that keep your eustachian tubes from working like they should.

Learn about the eustachian tube, a hollow structure that connects the middle ear to the pharynx. Find out how it helps regulate air pressure and drain mucous in the ear. Anatomy. Although commonly known as the Eustachian tube (after Bartolommeo Eustachio, an Italian anatomist, 1524-1574), the preferred name for this structure is the auditory (or pharyngotympanic) tube which better describes its anatomical relations. The Eustachian tube (/ j uห ห s t eษช ส ษn /), also called the auditory tube or pharyngotympanic tube, [1] is a tube that links the nasopharynx to the middle ear, of which it is also a part.In adult humans, the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter. [2] It is named after the sixteenth-century Italian anatomist Bartolomeo Eustachi.
